Objective:To observe the outcome of posterior staphyloma (PS) marginal retinal photocoagulation in pars plana vitrectomy (PPV) for high myopia macular hole retinal detachment eyes accompanied with PS.Methods:From January 2017 to June 2019, 49 patients (49 eyes) with high myopia macular hole retinal detachment accompanied with PS who were undergone PPV operation from Tianjin Eye Hospital were included in this study. There were 13 males (13 eyes) and 36 females (36 eyes). All patients underwent best corrected visual acuities (BCVA) and optical coherence tomography examinations. The standard logarithmic visual acuity chart was used for BCVA examination, and the visual acuity was converted to minimum resolution angle in logarithmic (logMAR) when recorded. The patients were randomly divided into two groups according to surgical options: conventional PPV with internal limiting membrane (ILM) peeling (group A, 24 eyes), PS marginal retinal photocoagulation in PPV with ILM peeling (group A, 25 eyes). The mean preoperative logMAR BCVA of group A and B were 1.87±0.28 and 1.80±0.37, the difference was not statistically significant ( t=0.604, P=0.551). The patients in the group A received 23G PPV, triamcinolone acetonide staining during the operation, the epiretinal membrane was peeled off, indocyanine green assisted staining, the posterior macular ILM was peeled off, and the peripheral retina was examined in detail during the operation. Areas with retinal degeneration were reinforced by laser photocoagulation, and the subretinal fluid was drained through the macular hole and filled with silicone oil. The eyes of the group B were subjected to retinal photocoagulation for 2 to 3 rows at the edge of the PS in addition to the usual surgical procedures. The average follow-up time was 8.34±3.21 months. Surgical outcome were estimated by the average number of operation, retinal reattachment rate, macular hole closure rate and BCVA. The χ2 test or Fisher exact probability was used to compare the count data. Independent sample t test was used to compare the measurement data. Results:Retinal reattachment was obtained in 17 eyes (70.8%, 17/24) and 24 eyes (96.0%, 24/25) in group A and B after first surgery respectively, the difference was statistically significant ( χ2=3.984, P=0.046). Final retinal reattachment was obtained in all 49 eyes. Final macular hole closure was in 15 eyes (62.5%, 15/24) and 19 eyes (76.0%, 19/25) in group A and B, respectively, the difference was not statistically significant ( χ2=1.051, P=0.305). The mean postoperative logMAR BCVA of group A (1.20±0.47) and B (1.08±0.39) were all improved than preoperative BCVA, the differences were all statistically significant ( t=2.899, 5.327; P=0.001, 0.000), the differences of mean postoperative logMAR BCVA between two groups was not statistically significant ( t=0.675, P=0.506). The mean number of operation of group A (2.63±0.88) was more than group B (2.08±0.28), the difference was statistically significant ( t=3.003, P=0.006). Conclusion:In comparison with conventional PPV, combined PS marginal retinal photocoagulation can improve retinal reattachment rate after first surgery, and reduce the number of reoperations.

Background:Pancreatitis is the main complication of ERCP,and a variety of risk factors will increase its risk. Studies showed that temporary pancreatic duct stent can reduce the incidence of post-ERCP pancreatitis (PEP). Aims:To study the efficacy and safety of prophylactic pancreatic duct stenting on preventing PEP in patients with risk factors. Methods:Patients undergone ERCP and accompanied with one or more PEP-associated risk factors from November 2013 to November 2016 at Huaibei People's Hospital were enrolled,and were divided randomly into pancreatic duct stenting group (observation group)and non-stenting group (control group). Serum levels of amylase at 4,24 and 48 hours after the procedure and incidence of PEP were compared between the two groups. Results:A total of 297 patients were enrolled, and 147 patients were in observation group,and 150 patients in control group. No significant differences in gender,age and ERCP disease spectrum were found between the two groups (P > 0. 05). Incidence of PEP was significantly decreased in observation group than in control group (6. 1％ vs. 16. 0％,P < 0. 05). Serum levels of amylase at 4,24 and 48 hours after the procedure were significantly decreased in observation group than in corresponding control group (P < 0. 05), however,no significant difference in incidence of hyperamylasemia was found between the two groups (59. 2％ vs. 54. 7％, P > 0. 05). Conclusions:Prophylactic pancreatic duct stenting may decrease the incidence of PEP in patients accompanied with PEP-associated risk factors, especially could decrease the severity of PEP. However, the incidence of hyperamylasemia is not decreased.

Objective To investigate the appropriate method in diagnosing precursor lesions of pancreatic cancer and its treatment. Methods From Jan. 2006 to Dec. 2007, 92 cases were operated for pancreatic neoplasms. Among them 7 cases had pancreatic precursors. The mucinous cystic neoplasm was found in 1 case, intraductal papillary mucinous neoplasm(IPMN) in 2 cases, endocrine tumor in 1 case and pancreatic intraepithelial neoplasia (PanIN) in 3 cases. CA19-9 level was tested by immunoflucence assay. All of the 7 patients were examined by CT. Endoscopic ultrasound(EUS) and endoscopic retrograde cholangio-pancreatography examinations were performed on 1 and 2 patients respectively. Results There was neither specific symptom related to these precursors nor any evidence of mass as revealed by CT or ultrasound. But dilatation and stricture of pancreatic duct were found in PanIN patients, and cystic dilatation of pancreatic duct in pancreatic head was present more in IPMN patients. For cystic neoplasms in pancreatic body and tail, they were commonly solid and isolated. CA19-9 level was slightly elevated in some patients but with no diagnostic value. Surgical resection was done with excellent result. Conclusion For the suspected pancreatic precursors, aggressive diagnostic approach and surgical resection will be the best option and can further prevent cancer development.

BACKGROUND:Nowadays, growth factors are commonly used to induce bone marrow mesenchymal stem cells. However, this is a high-cost method with a great amount of growth factors. In addition, the chondrogenic potential of bone marrow mesenchymal stem cells wil decrease significantly with increasing times of culture. OBJECTIVE:To observe the directed differentiation of bone marrow mesenchymal stem cells co-cultured with human synovial fluid. METHODS:Human bone marrow mesenchymal stem cells were isolated and cultured by adherence screening method. The synovial fluid of the knee was aspirated from healthy volunteers by aseptic operation. Passage 3 human bone marrow mesenchymal stem cells were co-cultured with the fol owing media:synovial fluid+complete medium;synovial fluid+bone marrow mesenchymal stem cells+complete medium;bone marrow mesenchymal stem cells+complete medium. The morphology and growth of the cells were observed under an inverted microscope every day. At days 7, 14 and 21 of induction, toluidine blue staining and immunocytochemical staining were performed.
RESULTS AND CONCLUSION:After co-culture with human synovial fluid, human bone marrow mesenchymal stem cells proliferated slowly, and varied from fusiform to oval or polygonal;toluidine blue and col agen II staining were positive. These findings indicate that the synovial fluid has a positive role in the chondrogenic differentiation of bone marrow mesenchymal stem cells. The synovial fluid may contain substances that promote the chondrogenic differentiation of bone marrow mesenchymal stem cells.
